Structure of lecithin:cholesterol acyltransferase with a covalent acyl-intermediate mimic and a small molecule activator reveals an active conformation and that the enzyme can be activated via its membrane binding domain.
Sponges and ctenophores lack hypoxia-inducible factors, suggesting that the metazoan last common ancestor could have lived aerobically under severe hypoxia and did not need to regulate its transcription in response to oxygen availability.
In a Ugandan birth cohort, early childhood infection-exposure, notably to malaria, helminths, and diarrhoea, is associated with lower prevalence of atopy and allergy-related diseases in later childhood.
Analyses of genetically engineered mouse models reveal the androgen receptor-independent properties of a luminal stem/progenitor cell in the prostate epithelium, and its ability to serve as a cell of origin for castration-resistant prostate cancer.
Profiling chromatin accessibility and nuclear transcription across Caenorhabditis elegans development and ageing generated the first map of transcriptional regulatory elements and their activities across an animal's life.
